I-IUMIDIFYING .ANP AIR-MOISTENING- APPARATUS.

Be it known that we, S'rUAirr W. Creamer: and WVILLIAM B. Hones, citizens of the United States, residing at Charlotte, 1n the .county ofMecklenburg and State. of North Carolina, have invented certain new and useful'Improvements 1n Hum difying and Air- Moistening Apparatus; and we do hereby declare. the following to be a full, clear,'and

exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

Our invention relates to means for moistening the air in rooms or factories, has for its object to provide an apparatus which will not only keep the air constantly supplied with any preferred amount of moisture and diffuse such moisture throughout the room, but will also perform the additional function of cleansing the air.

The invention consists in certain improvements in construction of the device shown in the patent to Stuart TV. Cramer,-#908,964, bearing date of January 5th, 1909, aswill be fully disclosed in the following specification and claims.

The accompanying drawing, which forms part of this specification, represents a vertical. section partly in elevation of our improved humidifier.

Reference being had'to the drawing and the designating characters thereon, the numer al 1 indicates the inner or spray casing within which is the spray nozzle 2. g

3 is the pan or collecting basin and 4: the

- deflecting cone.

5 is, a combinedstopcock and strainer for the water supply and 6 is the waste water strainer.

7 is the wrter supply pipe and S the-waste water pipe.

9, 9, are supporting hangers for the basin and 10,10, are supporting hangers for the whole apparatus.

11 arebails for the convenient handling ofthe casing 1. v

12 isan'outer casing inclosing the air space 12 between the inner-or spray casing 1 and the outer. casing 12.

13 are centering and carrying porters definitey and relatively fixing the position of the inner and outer casings with reference to each other and to the other parts of the apparat-us.

1 1 is a vertically movable supplemental venting. the

casing inclosing a plenum space 14 between the upper end of the inner spray casing 1 and the fan 15. v

' 16 is a support by which the fan is suspended in its position by the straps 10.

17 is a carrying member firmly fixed to the fan supporting member 16, to which the supplemental casing 1 1 is detachably secured with the bayonet joint 18'. I

19 is a pin attached to a .hanger'by a chain 20 and is used as a support for the. casing 12 in raised position by being thrust through a hole 21 in the hanger and upon which the lower end of the casing-12 rests' 2 is an auxiliary bell-shaped deflector,

rigidly attached to the-outer casing 12 by means of carrying porters 23. This deflector 22 separates the space between the? two bells into two passages 24 and 25.

26 represents anauxiliary or false bottom fastened to the pan 3 with its upper surface at an angle to that of the pan.

27 is an annular trough or basin to arrest water flowing down the inside of the casing 1 and is provided with a lip 28 forming an extension of the casing, which projects into the trough and forms an .efiectiveseal, corn polling the air issuing through the concentric passage 29 to pass under the lip and through the water in said trough, thus increasing the etliciency of the humidifier.

In endeavoring to increase the evaporative capacity of the humidifier shown in Patent 908,964, Fig. 1, it was found diflicult to go beyond a certain point on account of the increased volume of spray issuing from the pan, being drawn back into the fan and recirculated through the humidifier. This was found to be caused by too great a volume of air being deflected by the pan itself, and while. it was extremely necessary to divert a part of this current of air down on to the issuing spray so as to beat the large drops down against the pan, thereby prehumidifier from wetting down yet it was found when all of the air passing down through space 12' was de- 'flected against the edge of the pan as shown in the patent referred to, that the increased capacity could not be obtained. In order to still. retain the beneficial results attained by this outside shell of air beating down the large particles of water against the pan, we have arranged the auxiliary bell-22 which Still allows-a sufficient portion of this cur;
